I now have the trafficator working. Thanks to Colin, Nick and Peter for your advice in helping me understand the mechanism and what should be happening.
But the breakthrough happened as a result of thinking about A7JoJo's comment that he resolved the problem by fixing the insulation on the wire that runs to the bulb. I discovered that my wire had very dodgy insulation with poor attempts by some earlier owner to fix it. I soldered a new wire from the base of the coil up to the arm pivot. This gave a stronger driving force to push the arm all the way to the end of it's travel.
The arm still would not drop, though. Finally, I found that a small misalignment of the coil was causing friction on the plunger. Nudging the coil to the side has now allowed the arm to drop freely.
So all fixed without spending a dollar.
I spent about 8 hours getting to this final solution. But the exercise to the brain has been worth it. I heartily agree with comments on other posts about the mental benefits of taking on these tasks and not being defeated by them.
The next challenge is to find the where the ends of the trafficator cables were left after an earlier owner cut them to install flashers.
Thanks all.
